6BR cases and weights

[P1ZombieKiller]

Looking to improve my reloading techniques, and I’m building a 6br right now. I bought 300 Lapua cases, and I decided to weigh and separate them because I heard of people doing that. Does this really make a difference to someone like me? This is the first time I have ever weighed brass. Is this pretty typical weighs? Just for giggles, I took my Remington 260 brass out,still has 300 new) and weighed those. WOW… they were all over the place, with nothing grouping more than 18 in any weight, and the span was over 4.5 grains from top to bottom.

30 @ 125.6
41 @ 125.7
35 @ 125.8
38 @ 125.9
41 @ 126.0
34 @ 126.1
22 @ 126.2
64 @ everything else

I do not shoot competitively,but might enter a few events because I have always wanted to). I just want to get the most out of this gun. Should I just load the first 30 then shoot them to death, then load 41 and shoot them to death, so on and so forth?

When I go out to the range, I like to shoot 20-40 rounds each time out. I do not load at the range, so each time I would be coming back and reloading at my desk. Not sure it matters, but here are the gun specs:

Rem 700 trued action
Pac Nor 28” 1.25 straight with 1:8 twist
Jewell trigger set at 6 oz
McM A5 stock
Badger 20 MOA mount, Burris Zee rings, NF bench rest scope,still looking for scope).

I would consider the Lapua weights close, there all less than 1g apart,,per your numbers) and that's as good as it gets. So just separate them together by weight, it wont hurt, and may help a little.
For target loads, I keep all round in groups of 5, like in the case tray, and box. So that all 5 round in a row will have the same case weight,or close). As I shoot 5 round groups. Does that make sense?

P1ZombieKiller,

I shoot 600 yd IBS Benchrest. with a 6BRX I like to keep all my brass 0.5 gr to 0.6 gr spread, just depends on how it wieghts out. If this was my brass, I would keep all for record rounds, but the '64 everything'. You can use them for sighter rounds. Or just hold them for later, the next lot of brass may fall in where they weight.

I don't know how much weighting matters, but it make my feel better. Most of the times you are looking for the few that are way out of the norm.

For my 6 BR varmint guns I just shoot it from the box.
